Use the Microsoft Support and Recovery Assistant (SaRA)
When standard uninstallation through Windows Settings fails, the Microsoft Support and Recovery Assistant is the most effective tool to force-remove Office files and registry entries.
This official diagnostic tool is designed to resolve deep-rooted installation and uninstallation problems by bypassing standard removal procedures.
Visit the official Microsoft support website and download the Microsoft Support and Recovery Assistant (SaRA) installer.
Launch the downloaded setup file and follow the initial prompts to install the Assistant on your computer.
Open the application, select 'Office & Office Apps' from the list of products, and choose the option indicating you are having trouble uninstalling Office.
Select the specific Microsoft 365 version you want to remove and let the tool automatically clear all related files. Restart your computer once finished.
Temporarily Disable Security and Network Settings
Active firewalls, antivirus programs, VPNs, or proxy servers can interrupt the background streaming processes required during uninstallation.
Use the Office Deployment Tool (ODT)
Advanced users can utilize the Office Deployment Tool with a specific XML configuration to force the removal of Microsoft 365 products.

Frequently Asked Questions
What causes Microsoft 365 error code 30015-25?
This error is typically caused by corrupted streaming installation files, or interference from background security software such as active antivirus programs, firewalls, or VPNs during the uninstallation process.
Can I manually delete the Office folders in my C drive if uninstall fails?
Manually deleting the Microsoft Office folders from Program Files is highly discouraged. Doing so leaves behind residual registry keys and system files that can cause operating system instability and block future software installations. Always use the Microsoft Support and Recovery Assistant.
Do I need an internet connection to uninstall Microsoft 365?
Yes, standard uninstallation of modern Microsoft 365 products often requires a stable internet connection to communicate with Microsoft servers, verify the license removal, and update streaming components.
Will uninstalling Microsoft 365 delete my Word or Excel documents?
No. Uninstalling the Microsoft 365 software applications only removes the programs from your computer. Your personal files, documents, and spreadsheets saved locally on your drive or in OneDrive will remain completely safe.
